The idea of neutrosophic code came into my mind at that time when i was reading the literature about linear codes and i saw that, if there is data transfremation between a sender and a reciever. They want to send11and 00 as codewords. They suppose 11 for true and 00 for false. When the sender sends the these two codewords and the error occures. As a result the reciever recieved 01 or 10 instead of 11 and 00. Thisstory give a way to the neutrosophic codes and thus we introduced neutrosophic... Topics: neutrosophic code, finite field
Why are elements with tiny angles harmless for interpolation, but deadly for stiffness matrix conditioning? Why are long, thin elements with angles near 180o terrible in isotropic cases but perfectly acceptable, if they're aligned properly, for anisotropic PDEs whose solutions have anisotropic curvature? Why do elements that are too long and thin sometimes offer unexpectedly accurate PDE solutions? Why can interpolation error, discretization error, and stiffness matrix conditioning sometimes...

We represent finite group in the form of a graph, these graphs are called unit graph. Since the main role in obtaining the graph is played by the unit element of the group, this study is innovative. Also study of different properties like the subgroups of a group, normal subgroups of a group are carried out using the unit graph of the group. Topics: Finite Group, Commutative Ring, Graphs
Authors in this book for the first time have constructed nonassociativestructures like groupoids, quasi loops, non associative semirings andrings using finite complex modulo integers. Topics: algebraic structures, finite complex numbers

In this article one builds sets which have the following property: for any division in two subsets, at least one of these subsets contains at least three elements in arithmetic (or geometrical) progression. Topics: finite number, natural integer set
Finite Element Analysis (FEA) using Finite Element Method (FEM) wasdeveloped over 70 years to solve the complex elasticity and structural analysis problem incivil and aeronautical engineering. Application of FEA is being expanded to simulation inelectrical engineering also to solve the complex design problems. The circuit theory modelsfor designing transformers are not much accurate in determining the transformerparameters such as winding impedance, leakage inductance, hot spot temperature etc....

Lattice structures due to their low weight and high performance as structural elements have been widely used in different aerospace applications. In this paper, effective parameters on the design of anisogrid lattice conical shells are investigated. First, filament winding patterns regarding the desired axial strength is decided. Then, regarding geometrical relations, effective parameters in order to form the anisogrid cell are identified. Distance of circular ribs from each other has an...

The connection between PDEs and Geometry is well known. When the flow on smooth manifold is characterized as vector field then one would expect that the flow remains stable for time as much possible as we wish. But, this is too much a requirement several topological constraints will come in the way of such smooth flows. We have made a note of this fact interms of global solvability.

Due to the fact of immeasurable inner temperature ofinverter-fed traction motor, three-dimension finite element modelof part of rotor iron core and half a rotor bearing wereestablished. The convective heat transfer coefficient between theair gap of motor and rotor surface were calculated according tothe heat transfer and fluid mechanics theory. The influence oftemperature rise on the stator and rotor resistance wasconsidered for thermal loss calculation. The influence of the endof stator and...

In recent years, several computational models were published for the analysis of pipelines subjected to ice scour. With one exception, most of these models assumed uniform seabed soil properties. This paper studies the effects of different seabed soil stratigraphies on the ice scour process. Influence of various stiffer and softer soil sequences on the pipeline stresses are analyzed. Effects of reworking or remolding of soils by recurrent scours are studied. The question of existence of... Topics: Pipelines, Ice Scour, Finite Element Method
